Wolf crosses have been wrongly called coy dogs for decades before DNA testing came on the scene. Of course in this case I don't know for sure, just playing the odds.
Anything's possible, but that combination of Coyote and domestic dog is VERY unlikely. I grew up hearing the term "Coydog" long before there were any true Coyotes in this area but it was pretty much a generic term for domestic dogs that were feral. I've read publications that included documented fact that the Eastern Coyote subspecie as we know it is a result of Coyote/Timber Wolf crossbreeding. I've never read anything that had factual evidence of Coyotes breeding with domestic dogs.
